bvandeusenandClaude Opus 5.5 8eae3d3825 feat(syslog): pattern alerts: telling phrases counted per source each minute for alert rules, storage-trouble presets (#6001)

A pattern (phrases, a severity, a source, a window) is counted every minute
into plugin_metrics as lines_matching_<key> per added source, zero included,
so an ordinary alert rule fires on a match and clears once the window passes.
Each count reads only the lines stored since the last, by line id; a new or
changed pattern reads its window once.

Patterns page with ready-made storage-trouble presets and "Alert on it",
which opens the rule form aimed at the count. Source names are kept unique,
and a rename moves its counts and the rules on them.

bvandeusenandClaude Opus 5.5 51892a02c0 feat(syslog): a syslog receiver: UDP and TCP, senders offered before they're kept, each source's lines in a ring (#5999)

CI / integration (push) Failing after 1m35s

- plugins/syslog: RFC 5424 and RFC 3164 parsing, RFC 6587 TCP framing.
- Lines are queued as they arrive and stored every 5 s through a Holding,
  so a storage stall delays them rather than losing them.
- A new sender is an offered source, counted and not kept, until an admin
  adds it on the Syslog page (name, host); it can be ignored instead.
- The listener follows the plugin's settings (port, UDP, TCP), rebinding
  within seconds of a save; a port it can't open is said on the page.
- Hourly ring per source: age window and byte cap from Settings.
